MACHINE FOR FOLDING AND SHAPING TURN-DOWN COLLARS.

SPECIFICATION forming part of Letters Patent No. 642,660, dated February 6, 1900.

Application led March l0, 1899. Serial No. 708,588. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM A. ZEIDLER, a citizen of the United States, residing at New York city, in the county and State lof New York, have invented certain new and useful Improvements in Machines for Folding and Shaping Turn-Down Collars, of which the following is a full and true description, refer- 'ence being had to the accompanying drawings, illustrating a form of machine embodying my invention.

My invention relates to machines for folding and shaping turn-down collars, dac., for personal wear, and has for its object to provide a machine arranged to operate upon the collars continuously as they are supplied and to pass the finished collars out of the machine as a necessary part of lthe folding operation.

In the accompanying drawings I have illustrated one embodiment of my improvements.

Figure l is a side view of the new machine. Fig. 2 is an end view of the same. Fig. 3 is a partly-sectional view of Fig. l, and Fig. 4 is a top view of the machine.

The preferred machine has two uprights A and B, bolted to a base and joined near their upper ends by a casting C. The main operating-shafts D and E pass horizontally through said uprights, the rst-named shaft operatin g the shaping-disk and the second-named shaft operating the shaping-roller.

F is a toothed wheel for driving shaft D, and the shaft E is driven by a toothed wheel G. Wheels F and G mesh with and are driven by a toothed wheel H, mounted on a short horizontal shaft I. Said wheel H is driven by a wheel T, (see Fig. 4,) mounted on a shaft S, upon the end of which are the loose pulley K and the fast pulley J.

L is a conical shaping-disk mounted upon the front end of the shaft D by means of a `nut M.

N is a bevel-gear secured on the front end of shaft E, and this bevel-gear meshes with another bevel-gear O, and this latter drives a shaft (passing upwardly through extension P of upright B) engaging at its upper end with a shaping-roller Q. Said roller is (inthe preferred machine) disposed at an angle with relation to the conical disk L, Such an arrangement having been found by me to be practically desirable, especially for the shaping of collars. The roller is provided with an annular groove R, sloping at substantially the same angle as the edge of the conical disk L, and said edge fits into the groove Without contact at any point. The mechanisms for operating the disk L and roller Q are so correlated and arranged as to have the said disk and roller move at the same speed, simultaneously, and in the same direction.

The arrangement and relative posit-ions of the parts may be changed, the essential features (a conical disk, a roller disposed at an angle with relation thereto and having an annular groove into which the disk lits without contact at any point, and means for rotating the disk and roller simultaneously and in the same direction) being utilized.

The heating of the roller Q will materially assist the folding and shaping operations, and

said heating maybe done by means of a gaspipe U, the burner of which is in proximity to the interior of the roller. Other means for heating may be employed.

The shaft D is arranged to have not only rotary movement, but to have vertical movements in the uprights A and B, the arrangelnent being such that the conical disk L may be moved to and from the inclined roller Q without separating the gear-wheels F and H, thus enabling-the distance between the edge of theconical disk and the annular groove R of the inclined roller to be varied without stopping the rotation of the disk or roller, thus allowing insertion of the collar Without halting the machine.

In order that vertical movements may be given to shaft D, I have provided the rear upright A with a horizontally-sliding box V, operating against the tension of a spring WV, regulated bya set-screw X. A sleeve Y, surrounding the shaft,is arranged to have a slight oscillating movement in the boXV in any suitable manner. The forward upright B has an upward extension inclined atan oblique anglewith relation to the lower portion thereof and parallel with the angle of the conical disk and groove of roller Q. Said upward extension is provided with a sliding box Z, operating against the tension of a spring A', regulated by a set-screw B. A sleeve O', surrounding the shaft, is provided with pivotal pins D', (shown dotted in Fig. 1,) permitting the sleeve to have oscillating movements within and in relation to the box Z. Upon the shaft D there are two fixed collars X2 and Y2, one at either end of the sleeve C', for preventing the longitudin al movements of the shaft throughthe sleeve.

For the purpose of controlling the oscillating movement of the shaft and the separation of the conical disk and roller I have provided a rod E', passing upwardly through bridgepiece C and with its upper end abutting against a plate at the lower end of the box Z. The lower end of such rod carries a pivoted shoe F', arranged to slide in any suitable manner o n an arm G of the operating-lever pivoted at H'. For holding such arm G' down a rod I', carrying a weight J', may be employed. To raise such arm, a rod L', operated by a treadle, (not shown,) is secured to the opposite arm K of the operating-lever. In order to regulate the distance between the conical disk L and roller Q, I provide an adjusting device. A screw, such as M', passing through arm K' of the operating-lever and abutting against the lower edge of bridge C, may be advantageously employed for this purpose.

I have found it desirable to provide means for pressing the outer fold of the folded collar against the conical disk, preventing friction at the outer edge of tho annular groove of rollerQ, thus assistingin folding and shaping collars. For this purpose I prefer to use conical rollers N', mounted on pins carried by branches of a horizontal arm O', adjustably locked in engagement with an upright arm Q' by means of a screw P'. Said upright arm is adjustably fitted in a bearing R' of an overhanging base-piece S. Thus as the position of the conical disk L is adjusted the position of the pressure-rollers N' may also be correspondingly adjusted.

In order to assist in shaping the collar and for the purpose of returning the nished collar to the side wherefrom it was fed into the machine, I provide a collar-guide. This collar-guide B2, by preference a curved metallic plate, is secured in position by an arm A2, fitting a rod Z', which is vertically adjustable in frames W and X', secured to a vertical rod V', secured in an overhanging upright T'. (See Fig. 2.) The guide receives the collar as it leaves the conical disk and returns it to the workman.

While I have shown and described poweroperating connections for driving the machine, yet it will be understood that suitable hand-power'or foot-power connections may be used.

The collar after having been ironed is dampened at the line of fold and is passed end on into the machine. The edge of the conical roller folds it into the annular groove of the roller Q, and the pressure-rollers N' press the outer fold of the collar against the conical disk. As the collar passes out it is received by the guide and returned to the operator.
